Behovet av fysiska möten i en tidsålder av digital kommunikation : en studie i interkulturellt projektarbete
(Åbo Akademi, 2020)Dagens digitala kommunikationskanaler gör det lättare och snabbare än någonsin att föra en diskussion mellan människor på olika ställen. Även arbetsresor och fysiska möten är avgörande i kundrelationer. Denna avhandling ... -
Biological wastewater treatment in biofuel production in oil refinery by using a RBBR-bioreactor
(Åbo Akademi, 2018)The rotating bed biofilm reactor (RBBR) biologically treats wastewaters and it offers efficient solutions for removal of organic compounds, phenols and nitrogen. Its use avoids many of the problems and high needs associated ... -
Bipolar membrane electrodialysis of ammonium sulfate/bisulfate solutions : energy efficiency versus throughput optimization
(2023)To combat carbon emissions, carbon capture and storage becomes an increasingly urgent topic. The most common way of carbon dioxide capture and storage is geological storage in, for example, depleted oil or gas reservoirs. ... -
Carbon capture and storage feasibility in marine applications
(Åbo Akademi, 2020) -
Carbon dioxide capture from humid exhaust air and flue gases
(2022)Carbon capture and storage (CCS), as well as utilisation of carbon dioxide (CO2), has become an increasingly important research area in order to achieve the goals set by the European Commission for the EU to become climate ...Salassapidettävä 16/6/2026 asti. -

Catalysts for slurry-phase hydrotreating of bio-oil
(2021)The European Green Deal, a policy initiative set by the European Commission, aims to reduce greenhouse gas (GhG) emissions, and ultimately achieve an economy with net-zero GhG emissions by 2050. Achieving these targets ... -
Characterization of different tannins for possible industrial resin production
(2022)Tannins are the fourth most abundant component in plant material after cellulose, hemicellulose, and lignin, and have received extensive attention due to their high content of phenolic and carboxyl groups. The earliest use ... -
Characterization of Industrial Filter Materials for Improved Filter Medium Selection
(Åbo Akademi, 2019)Filter fabrics for solid/liquid separation have been analyzed and characterized in order to provide additional knowledge about said fabrics. Three different fabrics, AINO, MITO and ASKO have been studied in this thesis as ... -
Chemical addition to the wet web using foam application
(2022)Foam application is a promising new method for applying papermaking chemicals to wet paper webs. It is based on using aqueous foam as a carrier fluid and has simultaneously improved wet web runnability and furnish strength ... -
Coating of tannins on nonwoven substrates : formulation and coating evaluation
(2023)The demand for personal protective equipment, such as masks, is rising due to the new coronavirus. As awareness of sustainability increases, environmentally friendly bio-based products are attracting attention. Tannin is ... -
Compounding Toolbox for Polypropylene Film Recycling
(2021)The recyclability of materials and plastics in general has been discussed a lot in recent years. The majority of the plastic waste ends up in landfills and is being incinerated for energy. On the other hand, the recycling ... -
Control of the particle size distribution of a cement grinding circuit
(2021)For the past decades, the Blaine value has been the predominant characteristic when controlling the process parameters of a cement grinding circuit. The Blaine method measures the permeability of the cement, and therefore, ... -
Dealing with challenges in black liquor evaporation
(2023)The main objective of this thesis is to identify problems in black liquor evaporation that affect the evaporation economy. Evaporation of black liquor is a necessary process step to increase the dry substance content of ... -
Degradation of polydimethylsiloxane in simulated industrial process environments
(2021)Polydimethylsiloxane (PDMS) is commonly used in the Kraft process as an anti-foaming agent, which is added during the pulp-washing stage, where the pulp is separated from the black liquor. Crude tall oil (CTO) is later ... -
Determination of boiling heat transfer coefficients in plate heat exchangers
